The International Access Hub and the Collaborative Data Hub - Node 2 and Node 3 will continue to be accessible to their registered users, however the publications of the NTC products will be suspended for the whole duration of the maintenance window. The Sentinel-1 NRT products will continue to be published on the Collaborative Data Hub Node 2.
A temporary access hub will be activated for providing access to the last two weeks of Sentinel Data without registration. The temporary data hub will be available at the following address:https://tmphub.copernicus.eu/dhus

Complete Single Tile re-packaging of the historical Sentinel-2 Level-1C archive

05 Apr 2018

On 24 April 2018, a campaign will start on the Sentinel Open Data Access Hub and Copernicus Service Data Hub to republish the Sentinel-2 Level-1C products, from their historical format into the ‘Complete Single Tile' format introduced in December 2016.
Users who routinely automate the download of the new products should be aware that a significant volume of historical data will be published, and that these data may be re-downloaded automatically based on their ingestion date unless precaution is taken in the download scripts and workflows.
The affected dataset covers the sensing period from 04 July 2015 to 06 December 2016 (Sentinel-2A only). Approximately 340 thousand existing products will be repackaged creating over 1.3 million new products.
The republishing will cover the reformatting of the historical dataset of Sentinel-2A Level 1C products which do not feature either the Compact naming or the Complete Single Tile packaging characteristics, into their ‘Complete Single Tile' equivalent structure with the Compact naming representation.
The main features of the converted products as compared to their former counterparts are summarised below:

The radiometric and geometric quality of the products will remain unchanged. Coherently with this, the Processing Baseline identifier (PB) tagging every product will also remain unaltered (i.e. expected between PB 02.01 and 02.04), and will keep tracing the quality of the data outlined in the data quality report, in relation to the processing baseline.

(*) It is highlighted that PSD 14.2 used for the repackaging will provide continuity with the format introduced on 06 December 2016 and used up until the end October 2017. Consequently, the generated products will not embed the subsequent evolution of the product format introduced on 23 October 2017, starting with PB 02.06.
The intended strategy for the replacement; is to publish the re-packaged data in batches. A list of the replacement data and the corresponding new re-packaged data will be available, prior to the publication of each batch. Once the batch has been published, the old format data will be removed, subsequently.
Please stay tuned for more news, before the commencement of the campaign.

With reference to the news published on the 21st of March,
users are informed that the start of Maintenance 2 has been postponed to the 3rd of April 2018, 13:00 UTC.
The maintenance activity will be completed at 11:00 UTC of the 4th of April 2018.

During the maintenance window the following Data Hub Services will not be accessible:

The International Access Hub and the Collaborative Data Hub - Node 2 and Node 3 will continue to be accessible to their registered users however the publications of the NTC products will be suspended for the whole duration of the maintenance window. The Sentinel-1 NRT products will continue to be published on the Collaborative Data Hub Node 2.
A temporary access hub will be activated for providing access to the last two weeks of Sentinel Data without registration. The temporary data hub will be available at the following address:https://tmphub.copernicus.eu/dhus

Sentinel-3A data unavailability on 17 March 2018

23 Mar 2018

Due to an anomaly on 17 March 2018, all NRT/NTC/STC Level-1 and Level-2 user products are missing from sensing time 2:49:54 UTC to 14:39:44 UTC (absolute orbits impacted 10834-10835, relative orbits 81-82 of cycle 29). The issue is currently under investigation and further notifications concerning the nature of the anomaly will be released afterwards.

Data Hub major infrastructure upgrade activities: from 26 to 29 of March 2018

21 Mar 2018

As follow-up of the infrastructure maintenance activities performed at the beginning of March for upgrading the storage facilities, a new set of activities has been scheduled for improving the data access performances:

Maintenance 1: from Monday, 26 March 2018 to Wednesday, 28 March 2018

Maintenance 2: from Wednesday, 28 March 2018 to Thursday, 29 March 2018

The maintenance will affect the Data Hub services according to the following programme:

Maintenance 1: from Monday, 26 March 2018, 7:30 UTC to Wednesday, 28 March 2018, 14:00 UTC
During the maintenance window no service downtimes are foreseen, however it is expected a performance degradation on the search and download functions on the following data hub services:

The International Access Hub and the Collaborative Data Hub - Node 2 and Node 3 will continue to be accessible to their registered users however the publications of the NTC products will be suspended for the whole duration of the maintenance window. The Sentinel-1 NRT products will continue to be published on the Collaborative Data Hub Node 2.
A temporary access hub will be activated for providing access to the last two weeks of Sentinel Data without registration. The temporary data hub will be available at the following address:https://tmphub.copernicus.eu/dhus
The date of Maintenance 2 could be moved to the 3rd of April 2018 if the completion of Maintenance 1 goes beyond the scheduled window.

We apologize for any inconvenience caused.

Sentinel-3 data unavailability on 14 March 2018

15 Mar 2018

Due a planned out-of-plane orbit manoeuvre for Sentinel-3 on 14 March 2018, NRT/STC/NTC L1 and L2 user data could be degraded or missing in the following time interval:

This node offers the same data offer for the collaborative ground segment as the other nodes, including Sentinel-1 NRT data, with a three week rolling window. The node is operated in the GRNET centre and has access via standard internet and Geant. The node operates with a MTU 9000 (jumbo frames).

The third node is intended to replace Node-1 on the TSYS infrastructure, so we would like to advise all users of Node-1 to update their scripts/workflows to access this new node (or Node-2 on the OVH infrastructure). We would note additionally that the Sentinel-1 NRT data on Node-3 is synchronised with copy from the Node-1 so the unique identifier (UUID) for these data are the same on Node-3 as on Node-1 thus facilitating the transfer to this new node.

Pending the confirmation of overall performances for the collaborative data access, the Node-1 is intended to be dismissed at the end of March. A further news will be published to confirm the date.

Sentinel-1 new product format operational on 13 March 2018

13 Mar 2018

Sentinel-1 Level-1 and Level-2 products generated from 13th March 2018 will be processed with the new IPF version 2.90 and made available following the new product format, as announced on 12 June 2017 and on 13 October 2017.

Data Hub services resume operations

06 Mar 2018

The extended planned maintenance of the Data Hub infrastructure on 5 and 6 March 2018 has been closed, and all services have been resumed as of 09:00 CET today.

Unfortunately the upgrade of the storage infrastructure in view of the upcoming Sentinel-5P production, Sentinel-2 L2 global production and Sentinel-3B was not completed as planned, and a subsequent maintenance will be announced following the anomaly root cause analysis review with the infrastructure vendor.

The backlog of production publication that has accumulated during the maintenance period will be gradually recovered and we expect the nominal timeliness of the publication to be recovered within the next 24 hours.
